A TTORNEY Patented Mar. 3, 1936 gFrio 2 Claims.

This invention relates to pencils and the principal object of my invention is to provide a magazine pencil embodying a means for pointing the lead therefor from time to time when desired.

With the foregoing and other objects in view, as will appear as the description proceeds, the invention consists of the novel construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawing forming a part of the present application, in which:-

Fig. 12 is a sectional view of the top portion of the rack engagement means, illustrated in Fig. 10.

Like numerals of reference designate corresponding parts throughout the different views.

I5 is the body portion of my pencil, which is preferably cylindrical in form. This body portion may be exteriorly threaded at one end, as at I6, to receive a cap I1, which may or may not carry an eraser therein. 'Ihis cap I'l actsas a closure for one end of the body portion I5. I8 is the writing end portion of my pencil. This end is rotatably mounted in the end I5 of the body portion I5. In the disclosure Fig. 1, I have shown an annular groove connection to permit rotary movement of the writlng end portion I8 relative to the body portion I5 but I do not wish to be hunted to this particular interconnection between the writing end portion and the body portion, as many other methods of providing a connection permitting a rotary action of the writing end portion may be used with equally advantageous results. The outer end of the writing end portion is tapered and provided with a central lead exit orifice I9, as is common in pencils of this type.

20 is a guide member of substantially cylindrical form, with a longitudinal slot formed between its meeting edges, as shown as the top side in Fig. 1. This guide member 20 is held in transverse central position and in predetermined longitudinal position by means of the spacers 2| and 22, which spacers are notched to permit the rack, hereinafter. mentioned, to move longitudinally therethrough. 23 is a lead retaining member, preferably of cylindrical form and of a size to slide freely inside the guide member 20. One longitudinal meeting edge of the lead retaining member 23 is bent laterally to extend outwardly from the cylindrical portion thereof and is notched along its marginal edge to provide a rack 24. The leadretaining member 23 may be spot punched near its forward end to provide inwardly formed projections at a predetermined distance from the forward end thereof, so that the lead 25 may only be inserted a predetermined distance therein and will be frictionally retained in and carried by the lead retaining member 23. The lead retaining member 23 is in alignment with the lead exit orifice I9.

The means I have illustrated for moving the lead retaining member 23, comprises a sleeve 26 of resilient material and provided with a slot between the lower longitudinal marginal edges thereof, as illustrated in Fig. l. 'I'he body portion I5 is provided with a small longitudinal opening 21. The longitudinal side edges of the material in which the same is formed is preferably notched. The sleeve 26 is spot punched outwardly as at 28 to provide two small humps on the outer face thereof which humps will respectively engage in one or other of the notched side edges of the body material through which the opening 21 is formed. In view of the sleeve 26 being of resilient material and slotted longitudinally at the bottom thereof, it may be pressed downwardly in the body portion I5 to disengage the humps 28 and be moved longitudinally therein. The sleeve 26 is provided with a transverse opening 29 therein. 30 is a. band of substantially annular formation which has a snug ilt interiorly of the sleeve y 26. 3l is a. finger carried by and integral with the band 30. The end 3 I of the nger 3| extends inwardly of the band 30 and is designed to engage into the rack 24. The upper end of theA finger 3| may be provided with any desired finger gripping means 3|". The upper portion of the finger 3| protrudes through and is movable in the transverse slot 29. This portion of the finger 3| may be spot punched, as at 32, to provide a hump engageable in one or other of the notches 33 formed in the edge of the material in which the opening 29 is formed. 'Ihis hump 32 and the notches 33 will provide a means whereby the nger 3| may be retained in its desired alternative position in the opening 29. When it is desirous to move the lead 25 forwardly through the lead exit orifice I9, the finger gripping means 3| is turned sidewise so as to disengage the finger portion 3|' from the rack 24. When thus disengaged, the sleeve 26 may be moved backwardly to the position as illustrated in Fig. 8. 'I'he finger 3| is then turned in opposite sidewise direction so that the end 3| thereof will engage the rack 24. With a finger pressing downwardly and forwardly on the finger gripping means 3|", the sleeve 26 now interengaged with the lead retaining member 23 may be moved forwardly the desired predetermined distance. As they are moved forwardly, the humps 28 will resiliently move under the notched edges of the body portion in which the opening 21 is formed and, when moved the desired distance, will normally retain the respective parts in their then relative position to each other.

The construction so far described as embodied in this application is to disclose a complete pencil construction and means for retaining and moving the lead in a predetermined desired manner. I do not wish to be limited to this particular disclosure as hereinbefore described, as any other desired means or mechanism may be used for retaining the lead in a predetermined position relative to the body portion of a pencil of this type and embodying a means for moving it longitudinally therein. The feature and principal object of my invention is the lead pointing means as hereinafter described.

This lead pointing means comprises a plurality of cutter blades carried in the writing end portion I8 and adapted to be moved in such a mamner in relation to each other and in relation to the lead as to bring the cutting blades into cutting contact with the lead when so desired and to be moved out of contact with the lead when not required.

I herein shown one embodiment of my invention which consists of an annular band 34 fitting snugly in the writing end portion I8. The writing end portion I8 is provided with oppositely registering longitudinal slots 35 and 36 through which engagement members 3'I and 38, integral with the annular band 34, extend and may be moved. Carried by the annular band 34, I provide a plurality of cutter blades 39 which may be of various designs and shapes for pointing rthe lead 25 in a manner as hereinafter described. The shank portion 4D, between the cutter blades 39 proper and the annular band 34, are sufficiently resilient that when the cutter blades and the band 34 are moved forwardly from the position illustrated in Fig. 1 to the position illustrated in Fig. 2 the cutter blades will move towards each other and, when returned to the position illustrated in Fig. 1, the resiliency therein will return the cutter blades to normally contact the inner face of the annular portion of the writing end portion I8, as shown in Fig. 1. 4I is a disc positioned internally of the writing end portion I8 and provided with a transverse slot therein. When the cutter blades 39 are moved forwardly, the free ends thereof enter the transverse opening in the disc 4I and the disc 4| relieves the rotary strain imparted to the cutter blades 39 when the writing end portion I8 is rotated relative to the body portion I5 in which the lead 25 is held against rotation to cause pointing of the lead, when the cutter blades are in the position as illustrated in Fig. 2. It will be appreciated that before the cutter blades on the annular band 34 are moved to pointing position, the lead through the mechanism hereinbefore described or any other mechanism will be moved backwardly in the body portion so that the* cutter blades and annular member 34 may be moved forward to pointing position, after which the lead will be moved up into contact with the cutter blades to permit pointing thereof upon rotation of the l writing end portion I8.

The foregoing specification and annexed drawing disclose the preferred embodiment of my invention, but it is to be understood that minor changes may be resorted to in the commercial l adaptation of my invention without departing from the scope of the invention as hereinafter claimed.

What I claim as new is:

1. Amagazine pencil having a body, a tapered writing point section mounted for rotation relative to the body, a cutter section mounted for longitudinal movement within the writing point section and held against relative rotation with respect thereto, cutter elements resiliently carried by the cutter section and movable into relative cutting position by the wall of the tapered writing point section as the cutter section is moved in one direction, and means carried by the writing point section to receive and hold the cutter elements in cutting cooperation following their advance in the writing point section.

2. A magazine pencil including a body, a writing point section rotatably carried by the body, a

cutter section movable longitudinally of the writing point section, cutter elements resiliently carried by the cutter section and movable toward each other in movement of the cutter section in one direction, and a disk secured in the writing point section to receive the ends of the cutter elements in the advanced position of the latter and hold said cutter elements in relative cutting position.
